The T-piece is a standard three quarter inch galvanised plumbing T-piece. The tap is 8mm. I used two spanners, I could have used a 5mm socket to turn the tap as well. Not shown here is a 6.5mm steel drill bit, which is also required.

The bolt is 65mm long 8mm galvanised mild steel, and the washers are fender washers, I used three together because they were thin and I needed rigidity. Three nuts are needed.
